In order to clarify the cause of pressure loss increase in supercritical water gasification (SCWG) equipment, the pressure loss through a heat exchanger for the SCWG tubular reactor was measured and compared for chicken manure gasification and that of ethanol, which included no inorganic compounds. The reactor was operated at 600 oC, 25 MPa, and suspended activated carbon catalyst was applied. Reactor plugging was observed after pressure loss increase for the case of chicken manure....
